guys i have this real nice shake it .... 

it is a bigger one i just took it apart it is a real one ........    means heaver coil big magnet ....  has a reed in it and a supercap ...   NO BATTERIES EATHER

HUMMMM  ALREADY USEING KICK POWER........ DUH!!!!!!   LOL


IST

PICS LATER

must be a big cap too as it runs the led a wile from a few shakes ....      so  do this ....  power jt regular one charge super cap ... run ... cam unit power 500 leds from a dead battery

IST:

That's where I got my first supercap and very strong neo from during last year's earth battery experiments.  That is a good cap in there if it is like mine was.  A lot of good parts in there for the $3.00 I paid for it.  Hey, could you post the pics of your flashlight modification again?  I am working on one with 13 leds and I think my light is similar to yours.  That was a great idea you had there.  Better light, more light and longer with less.

Thanks for the Ha Ha's, the rocking chair sure took a belting. Now if they had made it using steel, I wonder how long it would have held up to a V8 engine going flat strap, that would be an excellent and interresting experiment.


Jim I know but i dont understand thats its also a  .01MFD also that all . I can go buy a .1uf and its really a 103 PF . At least thats what Google says.

Al, whats happened is, in the early days, when the company who made thiee ceramics decided to name them, they didn't go to all the electroonic manufactures, and talk about using a single uniform discription code, they just decided to call it their way, if their discription of their part made sence to them, too bad for the oppersition.
Then another manufacturer does the same, but not to be outdone, they call it a different thing, but in a way that dosent alter the actual capacitance itself, so as long as everyones electrical discription of their parts is correct and dosent cross any measurement boundaries, then theres not much anyone can do about it. The outcome is total confusion.

Believe me when I say this, many electronic engineers get confused, and I bet they all have a set of tables on their desks to cross reference these parts.

Download a cross reference capacitance chart and print it out and put it somewhere handy.

Yep, I agree, the current ceramic code need a good overhaul so it can be a simple thing to remember and understand.

Hi All

After getting somewhat confused over the cap values last night I ran across this site that explains it really simple at
http://www.geocities.com/g_wellwood/electronics/capacitors.html and it helped refresh my memory.

Thanks to all that posted,  attached is a capacitance equivalent chart as well if anyone needs it.

Regards,
Paul

yes bill i will re post it ...  soon 


i took the flashlight apart it is a 5.5v .33f super cap holds a bit  the led runs for  10 -15 seconds  it also has a bridge rectifier in it ... so it takes  both pos and neg from the coil flips it to dc ...  adds up to more ...   kicks must also play a roll ..... 

ist


just  a awsome pulse motor supply and trigger unit    jt it did some one say lol 




TIP .......    VCR HEADS ARE A GOOD SUPPLY FOR TPU COILS.... AND  HEAVY DUTY  PULSE MOTOR FLY WHEEL AND BEARINGS ....  REMOVE THE MOTOR ......  KEEP IT
